According to mkdir s man page     mkdir -m 777 dirname

You could write a simple shell script  for example      bin bash mkdir   1  chmod 777   1    Once saved  and the executable flag enabled  you could run it instead of mkdir and chmod     scriptname path foldername   However  alex s answer is much better because it spawns one process instead of three  I didn t know about the -m option

IMO  it s better to use the install command in such situations  I was trying to make systemd-journald persistent across reboots   install -d  -g systemd-journal -m 2755 -v  var log journal

When the directory already exist    mkdir -m 777  path to your dir   When the directory does not exist and you want to create the parent directories   mkdir -m 777 -p  parent dirs to create your dir

you can use following command to create directory and give permissions at the same time  mkdir -m777 path foldername

Just to expand on and improve some of the above answers  First  I ll check the mkdir man page for GNU Coreutils 8 26 -- it gives us this information about the option  -m  and  -p   can also be given as --mode MODE and --parents  respectively       set s  file mode  as in chmod   not a rwx - umask    no error if existing  make parent directories as needed  The statements are vague and unclear in my opinion  But basically  it says that you can make the directory with permissions specified by  quot chmod numeric notation quot   octals  or you can go  quot the other way quot  and use a your umask  Side note  I say  quot the other way quot  since the umask value is actually exactly what it sounds like -- a mask  hiding removing permissions rather than  quot granting quot  them as with chmod s numeric octal notation  You can execute the shell-builtin command umask to see what your 3-digit umask is  for me  it s 022  This means that when I execute mkdir yodirectory in a given folder  say  mahome  and stat it  I ll get some output resembling this                 755                   richard richard          mahome yodirectory             permissions                 user group      what I just made  yodirectory       owner group others--in that order                  where I made it  i e  in mahome       Now  to add just a tiny bit more about those octal permissions  When you make a directory   quot your system quot  take your default directory perms   which applies for new directories  its value should 777   and slaps on yo u mask  effectively hiding some of those perms   My umask is 022--now if we  quot subtract quot  022 from 777  technically subtracting is an oversimplification and not always correct - we are actually turning off perms or masking them    we get 755 as stated  or  quot statted quot   earlier  We can omit the  0  in front of the 3-digit octal  so they don t have to be 4 digits  since in our case we didn t want  or rather didn t mention  any sticky bits  setuids or setgids  you might want to look into those  btw  they might be useful since you are going 777   So in other words  0777 implies  or is equivalent to  777  but 777 isn t necessarily equivalent to 0777--since 777 only specifies the permissions  not the setuids  setgids  etc   Now  to apply this to your question in a broader sense--you have  already  got a few options  All the answers above work  at least according to my coreutils   But you may  or are pretty likely to  run into problems with the above solutions when you want to create subdirectories  nested directories  with 777 permissions all at once  Specifically  if I do the following in mahome with a umask of 022  mkdir -m 777 -p yodirectory yostuff mastuffinyostuff   OR  you can swap 777 for 0777 if you so desire  outcome will be the same  install -d -m 777 -p yodirectory yostuff mastuffinyostuff  I will get perms 755 for both yodirectory and yostuff  with only 777 perms for mastuffinyostuff  So it appears that the umask is all that s slapped on yodirectory and yostuff   to get around this we can use a subshell    umask 000  amp  amp  mkdir -p yodirectory yostuff mastuffinyostuff   and that s it  777 perms for yostuff  mastuffinyostuff  and yodirectory

Don t do  mkdir -m 777 -p a b c since that will only set permission 777 on the last directory  c  a and b will be created with the default permission from your umask   Instead to create any new directories with permission 777  run mkdir -p in a subshell where you override the umask    umask u rwx g rwx o rwx  amp  amp  mkdir -p a b c    Note that this won t change the permissions if any of a  b and c already exist though

install -d -m 0777  your dir   should give you what you want  Be aware that every user has the right to write add and delete files in that directory
